Girard falls into the same "safe bet" category as Landy and Mikko (before he broke out last year and this year).
You know what you're going to get form him, and you know that what he's shown early in his career isn't an anomaly, or that he's gonna fall back to earth. Like Landy and Mikko, he's a very good two way player, he's very competitive and driven, and he's going to stay at least at the level he's at now, if not get better.
The only concern I have is durability in the playoffs, when the hitting picks up. He's been injured in the first few games of the playoffs two years in a row now.
Hopefully that's just a coincidence, or that he can bulk up a bit (not sure how much more he physically can without PEDs) and that it won't be a big problem going forward.
I don't think he signs long term for a number in the $4M range though. He played all year on the top pair, and looked pretty good.
I think you gotta start with a $5M number to get a long term deal done early this summer. I'd be on board with a 7 x $5M contract. Perhaps a bit more. The Avs seem to like settling on 7 years, like they did with Landy and Nate.
